ECU signal for fuel and temp...? I have searched and I can't seem to find this info.
I need to get a bit of information about the ECU or even where I can find this info.
I am looking for a place in the car (was hoping ECU) that I can tap into to get the signal that tracks the fuel level and the temp level of the car. That is, I want to get the signal that is going to the 2 guages in the cluster that tells these 2 bits of information.
Anyone know where I can find this signal? And if I can, are they a voltage or digital signal from a sensor somewhere?
Any suggestions?

Rep Power: 0 The temp can be found on the ECU RED/WHT wire on the B connector Pin 8
And also on the Multiplex unit
Anyway its a voltage between 0.1-4.8V depending on the temperature
The Fuel level indicator signal can be found at least behind the gauges YEL/BLK wire on the A connector Pin 8
The resistance of the pot in the FGSU and positions on the gauges are the following
F: 11-13 1/2: 68.5-74.5 LOW: 113.4-128 E: 130-132
The FGSU is fed with 5-8V so you do the math on the voltage level...
